Description

Technical Field

[0001] The utility model relates to the technical field of coated asphalt raw material processing, and specifically relates to a coated asphalt raw material processing device. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbon compounds with different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, mostly existing in the form of liquid or semi-solid petroleum, with a black surface and soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof and anti-corrosion organic cementing material. Coated asphalt is commonly used in paving roads. When paving stones on the road surface with coated asphalt, during raw material processing, the asphalt raw material needs to be heated and stirred to melt the asphalt and then coat it on the surface of the stones for normal use.

[0003] A coated asphalt raw material processing device with the patent number CN116440735A disclosed in the Chinese patent includes a stirring bin and a stirring component. The stirring component is arranged inside the stirring bin. The stirring bin is provided with a stirring bin heating component, and the stirring component is provided with a stirring paddle heating component. Compared with the prior art, the present invention not only has a heating device in the stirring bin, but also has spiral heating sheets on the stirring paddles, realizing simultaneous heating of the inside and outside of the asphalt. Moreover, the spiral heating sheets do not affect the stirring resistance during stirring and can also play a certain stirring role, making the heating uniform and improving the heating efficiency, having the value of popularization and application.

[0004] After the above device finishes stirring and melting the coated asphalt, since the viscosity of the melted coated asphalt is relatively high, it is impossible to cleanly discharge the melted coated asphalt from the stirring bin. After use, the inside of the stirring bin needs to be cleaned, and the cleaning difficulty of the coated asphalt is relatively high, which is inconvenient to use. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a coated asphalt raw material processing device, which has the characteristics of cleanly discharging the melted coated asphalt in the stirring bin and avoiding cleaning the melted coated asphalt in the stirring bin again.
